MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF is identified as malicious by multiple heuristics, including a machine learning classifier and ClamAV, and is flagged as an image-only lure. It contains an embedded URI pointing to 'seumenha.ru', which is highly suspicious. The document body is heavily obfuscated, but the presence of the external URI and the heuristic firings strongly suggest a phishing or malware distribution attempt.
